The Federal Reserve is still price-fixing the cost of money and artificially boosting the stock market, Peter Boockvar, chief market analyst at The Lindsey Group, told CNBC on Tuesday, as central bank policymakers begin their two-day meeting.

"Central banks want to think that things are positive, that it puts 'beer goggles' on investors' eyes," Boockvar said in a "Squawk Box" interview. "If you look at 2013, we've had pretty sluggish and mediocre growth. We've had low single-digit earnings growth, but we've had another massive gain in the stock market. And that's because of central bank largess."

The Fed is scheduled to conclude its September meeting Wednesday, and many economists believe it will announce the start of tapering its $85-billion-a-month bond-buying program.

The economy isn't doing better, according to Boockvar, because consumers are nervous about their salaries. "Statistically, the government tells us that inflation is very low, but incomes are not keeping up with the cost of living."
